Ireland have slipped to seventh in the latest IRB World Rankings, following yesterday's 12-8 loss to Scotland in the RBS 6 Nations Championship.
Wales continued their climb back up the rankings with a one place elevation to sixth on the back of their victory in Italy and Ireland's defeat in Murrayfield.
The Welsh had fallen to 10th - equalling their lowest ever ranking - before ending an eight-match losing streak with a win over France a fortnight ago, but now sit just under half a rating point below France in fifth.
Had Ireland managed to capitalise on their complete dominance of possession and territory then Wales would have remained seventh after the 26-9 win over Italy.
Ireland's second defeat of the Championship now leaves them just over half a rating point above Samoa and Argentina below them, while back-to-back wins for Scotland mean they are within a point of the Declan Kidney's side now.
Scotland remain 10th and now have Tonga beneath them after Italy fell one place to 12th on the back of the Welsh defeat. The Azzurri, however, are still more than three rating points above Fiji below them.
England have also strengthened their position as the leading northern Hemisphere nation in the rankings following the 23-13 win over France at Twickenham.
Stuart Lancaster's men now sit just over four points above France and are gradually closing the deficit to Australia above.
